linux 编译运行c文件

在ubuntu安装gcc

编辑 test.c

/* Not stdio.h */#include <unistd.h>void main(){char str[100];/*Write on screen*/write(1,"\nType Something : ",17);/*Read at most 100 chars from console into 'str' */read(0,str,100);write(1,"\nYou typed :\n",13);/*write 10 chars from 'str' to screen */write(1,str,10);/*newline*/write(1,"\n",1);}

# gcc -o test test.c

完成后会出现一个可执行文件test，这就是编译好的文件，直接./test 就可以执行了！
